USDA Pressured to Regulate Commercial Bumble Bee Industry

USDA Pressured to Regulate Commercial Bumble Bee Industry

In the early 1990s, the USDA conducted risk assessments of
the interstate transport of bumble bees for commercial greenhouse pollination,
particularly tomatoes. Because of the risk of introducing non-native pests and
diseases into new areas, they concluded that commercially reared bumble bees
should not be shipped beyond their native range (They also prohibited the
importation of bumble bees from outside the country, with the exception of Canada). At the time, it seemed a
simple solution to growing concerns that the fledgling industry had taken off
before adequate regulatory measures were put in place.

There was already some concern that
the genie had gotten out of the bottle. Between 1992 and 1994, queens of two North American
species-Bombus impatiens and Bombus occidentalis-were sent to Europe where they
were reared in facilities along side European bumble bees. The colonies were
then shipped back to the United States and distributed for crop pollination.

Fast forward to 1997. The
commercial bumble bee rearing industry in North America suffers such
catastrophic losses of Bombus occidentalis, a western bumble bee that it wipes
out nearly its entire stock. In the following years, scientists begin to
observe the precipitous decline of several North American bumble bee species,
all belonging to the same subgenus. Dr. Robbin Thorp, a bee researcher and
Professor Emeritus at UC Davis, upon learning of the commercial declines
wonders if there is some connection. Could the wild bees be dying of the same
disease that swept through commercial facilities?

Thorp has come up with a thesis:
that the recent decline of four North American bumble bee species is the result
of a pathogen brought into the country by bees that were shipped to Europe. In
short, he argues that the North American bees acquired a selectively virulent
strain of Nosema bombi, a gut pathogen, while being reared alongside the
European bumble bee Bombus terrestris. When the bees were sent back to the US
and distributed, the pathogen made its way into the wild, decimating several
closely related species.

This all ties back to the USDA's
attempt to regulate the interstate shipment of bees because, in 1998, after
commercial stocks of Bombus occidentalis were wiped out the industry was left
with a single North American product: Bombus impatiens, an eastern bumble bee
whose range extends from Maine to southern Florida. In 1998, USDA, against its
own risk assessments, allowed the shipment of impatiens throughout the country.
The largest greenhouse tomato-producing states - Arizona, Texas, and Colorado -
are all states in which the bee is not native. It has been well documented that
commercial bees can easily escape from greenhouses if necessary precautions are
not taken.

In a story that I wrote
for Earth Island Journal last fall, Wayne
Wehling, senior entomologist at the USDA-APHIS, said that they still agreed
with their earlier risk assessments.

"Certainly we have been
all over the board with that," he told me. "And I think we've been all over the
board largely because of the lack of clarity in the regulatory authority as to
what our capacities really are."

To help clarify what the USDA
Department of Animal Plant Health Inspection Service should be doing to protect
our wild bees, the Xerces
Society, a non-profit conservation group that focuses on protecting
invertebrates, has filed a petition asking the USDA to regulate the
interstate movement of bumble bees and to require that commercial breeders
demonstrate that their bees are disease free. Along with the NRDC, Defenders of
Wildlife, and Dr. Thorp, they write that, "The continued shipment of bumble bee
pollinators to areas outside of their native ranges poses a grave threat to the
wild populations of closely related bumble bee species. Without better
regulation, we are likely to continue to see catastrophic declines, and
possibly extinctions, of bumble bee pollinators."

APHIS is under no obligation to
respond but Sarina Jepsen, Endangered Species Program Director at Xerces said
in an email that, "Our hope is that pressure from various sectors (scientists,
conservation orgs, sustainable agriculture groups, policy makers and others)
coupled with this petition will encourage them to promulgate new regulations." According
to USDA-APHIS, they are currently reviewing the petition to "determine our
response." Perhaps when they do respond, they'll better clarify their regulatory
authority.

In the vile wake of Charlottesville - those sweaty young white men, pasty faces contorted, screaming, "Blood and Soil!" "Jews Will Not Replace Us!" "Fuck You Faggots!" - what to say? Just this: This is racism, domestic terrorism, pure hate. This is not who we are, and this is not ok. Most vital, those "whose pigmentation matches theirs" must speak "with unflinching clarity (or) we simply amen it... They need white faces speaking directly into their white faces, loudly on behalf of love."
